Switch zoning limitations for the EMC Symmetrix and Symmetrix DMX

There are limitations in switch zoning for the Storwize® V3500 and the EMC Symmetrix and Symmetrix DMX systems.

Switch zoning

The Storwize V3500 switch zone must include at least one target port on two or more Fibre Channel adapters to avoid a single point of failure.

The EMC Symmetrix and Symmetrix DMX must be configured to present logical units (LUs) to all Storwize V3500 initiator ports that are in the fabric zone.

Only Storwize V3500 initiator ports that are LUN masked on the EMC Symmetrix or Symmetrix DMX controller should be present in the fabric zone.

Note: The EMC Symmetrix and Symmetrix DMX systems present themselves to the Storwize V3500 clustered system as separate controllers for each port zoned to the Storwize V3500 system. For example, if one of these storage systems has 4 ports zoned to the Storwize V3500 system, each port appears as a separate controller rather than one controller with 4 WWPNs. In addition, a given logical unit (LU) must be mapped to the Storwize V3500 system through all controller ports zoned to the system by using the same logical unit number (LUN).

Connecting to the SAN

You can connect a maximum of 16 EMC Symmetrix or Symmetrix DMX ports to the Storwize V3500 system. There are no further special zoning requirements. Configurations that are set up to adhere to the requirements that are described in previous Storwize V3500 releases are also supported, but should not be followed for new installations.
